2 Claims.

This invention relates to a device for remixing carbonated water and the like, the general object of the invention being to provide a tube through which the liquid passes from a carbonator to a 5 cooler, that part of the tube inthe cooler having one or more loops therein for dividing the stream of water and then bringing the two parts together again, so that carbon dioxide and water coming from the carbonator is re-mixed after it leaves the carbonator,

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in therein.

Figure 4 is a section on the line 4-4 of Figure 1. 'In this drawing the letter A indicates a tube or so conduit for leading carbonated water or the like tinues from this loop as shown at 2 to a second through the perforations 6.

from one container to another, such as from a carbonator to a cooler B. That portion of the tube orpipe in the cooler is formed with a substantially circular loop I and then the pipe or tube conloop 3. This second loop is formed at the outlet end of the pipe or tube and is formed with a slot 4 at its bottom for the discharge of the liquid into the cooler. A substantially cylindrical member 5 having perforations B therein is connected with the lower end of the loop 3 and extends horizontally and receives the liquid passing from the slot 4, the ends of the cylinder 5 are open so that the liquid can pass from these ends also As shown in the drawing each loop forms a pair of substantially arcuate-ehap-ed branches connected at their ends with the straight portions of the tube and each branch is of substantially the same diameter of 5 said straight portions.

As the liquid reaches the first loop it is divided and some of the liquid flows along one part of the loop and some along the other part, with the two A parts coming together at the bottom of the loop .55 where the liquid passes into the straight part 2.

The separation of the liquid and the coming together again of the two parts thereof causes a thorough mixing of the liquid so that the carbonated liquid or the like is thoroughly mixed and the same action is repeated in the second loop 3 and also the mixing is continued by the passing of the liquid through the slot 1 against the member 5 and through the ends and perforations of said member, The liquid enters the cooler from the member 5 and the liquid leaves the cooler through the outlet pipe (1 which leads the liquid to the fountain.

As is well known carbon dioxide is mixed with water in a carbonator to form seltzer. The mixture is then passed to a cooler where it is cooled and from time to time some of the contents of the cooler is used at a soda fountain for mixing with various drinks dispensed at the fountain. Very often the seltzer becomes flat in the carbonator because the mixing process therein is not continued but depends upon the level of the carbonated water in the carbonator. This device causes a remixing of the carbon dioxide with the Water in the cooler. This re-mixing by the invention makes the carbonated water stronger and causes it to retain its strength for a longer period of time after being drawn from the fountain. The use of the invention also results in the saving of carbon dioxide since less pressure is needed in forcing the gas into the carbonator. The loops in the device cause the water with the carbon dioxide therein to separate into two streams and then the two streams come together again, thus causing a re-mixing of the carbon dioxide with the water. As it escapes from the device a further re-mixing takes place. The device is an accessory to the carbonator and'it acts to re-mix the water and carbon dioxide after the mixture has left the carbonator.

In some cases it is not necessary to use the member 5 and also the first loop may be eliminated and if desired the tubing can be bent upwardly after it enters the cooler so that the looped portion is directed upwardly in the cooler.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:

1. A remixing device of the class described comprising a conduit having a loop therein for separating the fluid passing therethrough into two parts, with the parts uniting again at the outlet end of the loop, the outlet end of the loop having a discharge opening therein, and a perforated tubular member connected with the outlet end of the loop and extending at right angles to the tube and having its ends open,

2. A re-mixing device of the class described comprising a conduit having a loop therein for separating the fluid passing therethrough into two parts, with the parts uniting again at the outlet end of the loop, the outlet end of the loop having a discharge opening therein, and a perforated tubular member connected with the outlet end of the loop and extending at right angles to the tube and having its ends open, and a second loop in the conduit for separating the fluid passing therethrough in the two parts, before the fluid is separated by the first loop, the two loops being spaced at considerable distance apart.
